Symfony Propel Query - symfony1

Question

I want to make this query on Symfony/Propel
SELECT
folders.NAME,
COUNT(documents.NAME),
COUNT(files.idfiles),
SUM(files.size)
FROM `folders`
LEFT JOIN `documents_has_folders` ON (documents_has_folders.folders_idfolders = folders.idfolders)
LEFT JOIN documents ON (documents_has_folders.DOCUMENTS_IDDOCUMENTS=documents.IDDOCUMENTS)
LEFT JOIN files ON (documents.IDDOCUMENTS=files.DOCUMENTS_IDDOCUMENTS)
GROUP BY folders.idfolders
I do this query
$x = FoldersQuery::create()
->addSelectColumn(FoldersPeer::NAME)
->addSelectColumn("COUNT(".DocumentsPeer::IDDOCUMENTS.")")
->addSelectColumn("COUNT(".FilesPeer::IDFILES.")")
->addSelectColumn("SUM(".FilesPeer::SIZE.")")
->addJoin(DocumentsHasFoldersPeer::FOLDERS_IDFOLDERS, FoldersPeer::IDFOLDERS, CRITERIA::LEFT_JOIN)
->addJoin(DocumentsHasFoldersPeer::DOCUMENTS_IDDOCUMENTS, DocumentsPeer::IDDOCUMENTS, CRITERIA::LEFT_JOIN)
->addJoin(DocumentsPeer::IDDOCUMENTS, FilesPeer::DOCUMENTS_IDDOCUMENTS, CRITERIA::LEFT_JOIN)
->addGroupByColumn(FoldersPeer::IDFOLDERS)
->find();
This returns:
500 | Internal Server Error | PropelException

Why there is no table on FROM??? Why it creates a wrong query?
Thanks a lot.
EDITED:
Same problem have and if i do the query like this:
$c = new Criteria();
$c->addSelectColumn(FoldersPeer::NAME);
$c->addSelectColumn("COUNT(".DocumentsPeer::IDDOCUMENTS.")");
$c->addSelectColumn("COUNT(".FilesPeer::IDFILES.")");
$c->addSelectColumn("SUM(".FilesPeer::SIZE.")");
$c->addJoin(DocumentsHasFoldersPeer::FOLDERS_IDFOLDERS, FoldersPeer::IDFOLDERS, CRITERIA::LEFT_JOIN);
$c->addJoin(DocumentsHasFoldersPeer::DOCUMENTS_IDDOCUMENTS, DocumentsPeer::IDDOCUMENTS, CRITERIA::LEFT_JOIN);
$c->addJoin(DocumentsPeer::IDDOCUMENTS, FilesPeer::DOCUMENTS_IDDOCUMENTS, CRITERIA::LEFT_JOIN);
$c->addGroupByColumn(FoldersPeer::IDFOLDERS);
Again after FROM there is no table...

This is not the Propel way to build queries since Propel 1.6 (maybe before). We don't use Criteria nor Peer classes. The following query:
SELECT
folders.NAME,
COUNT(documents.NAME),
COUNT(files.idfiles),
SUM(files.size)
FROM `folders`
LEFT JOIN `documents_has_folders` ON (documents_has_folders.folders_idfolders = folders.idfolders)
LEFT JOIN documents ON (documents_has_folders.DOCUMENTS_IDDOCUMENTS=documents.IDDOCUMENTS)
LEFT JOIN files ON (documents.IDDOCUMENTS=files.DOCUMENTS_IDDOCUMENTS)
Can be written like that:
$query = FoldersQuery::create())
->joinDocuments('documents')
->joinFiles('files')
->withColumn('COUNT(documents.NAME)', 'CountName')
->withColumn('COUNT(files.IDFILES)', 'CountIdFiles')
->withColumn('SUM(files.size)', 'Sum')
->select(array('Name', 'CountName', 'CountIdFiles', 'Sum'))
;
It may requires adjustments but it's the right way.
